  • Dead on arrival
I was so excited to replace my old roomba with this self emptying one. It took alittle over a week to get here with Prime, open it up, get the app, everything goes awesome, than I turn it on. It goes 2 feet and says there is a cliff, in the kitchen, on white tile. I Reset, clean side sensors, run the self clean hoping that would do something. Nope. Sooo disappointed. I'm returning it, but already put in an order for a replacement. If this one gets here faster and works, I'll update this review. Update: The first one was a i3560, and I returned it and got a i3550, strange BOTH were the same listing. The first one didn't work right out of the box as stated. The SECOND one didn't have the mapping feature at first, but after about an hour, it showed up, and had a new firmware version. My old 600 series lasted 14 years, and while I had to clean it, it was bulletproof. I'm hoping I will be as happy with this one. I am upgrading my review to a 3, and if it works for a year with out issue, I'll give it a 5. Why they are shipping two differant models, 3560, and 3550 under the same listing is beyond me. The first one came from a vendor and it had one of the plastic stickers cut before I got it ( 3560), the second one shipped straight from Amazon (3550) and honestly, it is working perfectly. The firmware just took alittle time to update. EDIT: It's run 2 days in a row flawlessly. If you order one, I'd try to get it direct from Amazon. Since there are so many bad reviews, I thought an update was warranted. ... show more

  • This is a real time saver
I always thought these were gimmicky. But I got one for Christmas and liked it so much I bought 2 more. I have all hard flooring, no carpets, and 2 dogs, a cat, and two birds that all contribute to mess. So I had to sweep everyday or I'd get those pet-hair tubleweeds blowing around. Having to sweep all the time I get lazy and let it go; or when I do it I spend an hour or 2 sweeping or vacuuming. These robots save me hours of time and get the job done better because they are relentless. I set them on a schedule and they do it everyday completely. I have one robot that I manually have to empty the cup everyday. He's in the bedroom, since I'm in that room every day that's convenient enough and only takes 2 minutes. I bought an i3+ and an i4+, they self empty and I have to change the bag about once every 2-4 months. I don't mind the cost of the vacuum bags because they give me so many hours of my time back. The first one I got is the little guy. The little guy's name is Finigan. Finigan isn't too smart. He vacuums in a random pattern. I started with him in the main part of the house. He did a great job but his battery usually ran out before he considered himself done. So the space is a bit more then he likes. He did a great job though. But I loved it so much I got more to cover the whole house and moved him to the smaller bedroom area. In the bedroom suite (bedroom + bathroom~350sq ft), he spends about 45 minutes zipping around to cover everything. When his battery is low he docks himself. I have to empty his cup everyday. At first his cup was usually about 3/4 full to full. The first day it filled and he stopped. I had to empty it and re-start him. After a few months of daily vacuuming, the cup is about 1/4 full each day. So I switched him to a MWF schedule. He's still about 1/4 to 1/2 full each use. He even goes under the bed and keeps that clean. It's really great. The i3+ is Dixie. Dixie does the downstairs. Dixie is smart. She goes in straight line patterns and covers the entire space using a very planned straight line methodical routine. The first day she poked around learning. It was about 1.5 hours. After that, the entire job was planned out and she did the whole thing in about 45 minutes. She has no problem when certain doors are opened vs closed. When it's open, she goes in and vacuums. If it's closed, she skips it. Her cleaning time varies from about 45 minutes to 1hr 15minutes depending on whether the extra rooms are included (doors open vs closed). She drives back to her base when done and docks. And the base sucks out what she collected. I love the base, it means I do not have to tend to her everyday. I actually only need to change the bag about every 3-4 months. There's not a lot going on downstairs. The litter box is there and so the cat pays visits. But we aren't down there daily tracking things around. Thanks to Dixie, there's no fur balls, hair-tumbleweeds, dust, or dirt. Always a nice clean floor. It's awesome. Her map in the app shows where she found 'extra' dirt. Usually right in front of the litter box. It's so awesome not having to sweep up litter daily. I have her on a MWF schedule too and that is more than enough to keep the place clean. I recently got Nick, an i4+ for the upstairs. He's quieter. He's like Dixie in is planning and map reporting, so he's smart. It's very cool. He also gets the job done quickly. First day was like 1.5 hours learning. Now he's done in 50 minutes. The base sucks everything out so I don't have to tend to him as much as Finigan. He's in the main part of the house and it gets the most dirty. The dogs spend all there time here. The cat is up here most of the time. And we have two birds who send seeds everywhere. It's amazing how far from the cage those birds can flick seeds. And their feathers and drift everywhere too. Nick takes care of all that. I do need to manually get under the couch and behind and under furniture which I do once every month or so. But this robot is awesome. Saves me the day in and day out sweeping and vacuuming. Having robots spend 3+ robot labor hours each day vacuuming is an awesome human labor saver. Once they've hit the whole house for a month or two I'm able to step them back to MWF schedules. Their brushes do a great job in the corners, better than me sweeping or vacuuming; mostly because they hit those corners every day and spend the time swirling that brush to work on it. That constant day in day out effort pays off over time. I really can't imagine going back to manually doing this. I look back at the hours I spent doing it thinking that was Neanderthal days. I look forward to telling my grand kids how I used to walk to school uphill in the snow everyday, dial rotary phones, select music off of CD's I had to manually put into a machine, and now, that I spent hours sweeping the floors in the good old days. ... show more

  • A game changer for those with busy lives
I hate making time for vacuuming the home, and I'm not able to afford hiring someone else to do it. Yes these devices are sort of pricey, but I purchased mine during the end of year holiday discounts and I'm certain this was a worthwhile investment. I did some research on the features and concluded the i3+ model was the sweet spot for my budget and available features. My floors are mostly hard surface (wood and tile) with a scattering of area rugs. Roomba manages the larger area rugs with no difficulty but it clearly doesn't like the smaller or lightweight rugs and spot rugs. I simply take 5 minutes to go around and pick up the lightweight rugs along with other obstacles like trash cans, bathroom scales and pet bowls in order to maximize the cleaning process. I also searched out all power cords that could pose a risk of entanglement and secured them out of the way - a one time effort in my opinion. The 850 sq ft space I focused Roomba on is complicated in terms of room geometry and furniture layout. It takes Roomba over two hours to clean it, with a recharge pause in the process. This limitation in battery capacity is why I rated battery life at 3, but for those with smaller and less complex spaces the one hour battery capacity limit wouldn't present itself. Bottom line - it cleans very well. The result is awesome - the floors are visibly clean, and the two hour process doesn't matter to me since I have plenty of other things I'd rather be doing. I highly recommend getting the iRobot+ models so you don't to deal with emptying the waste bin. I never saw Roomba get stuck or tangled up, confused or unable to navigate its way through the maze of furniture legs and doorways. It is persistent and thorough - exactly what I expected out of a robot. ... show more

  • I3+ is a lemon (updated)
UPDATE: 21 AUG 2026. It is still a lemon. Two days ago I got sick of all of the stuck bumper errors and disassembled to Roomba to look for a problem. I did not find it, and it worked the rest of the day with no issue. This morning the base station was blinking red and it did not run yesterday. I looked at it, the bag was not full, there were no obvious issues with the vacuum, so I put it back on the cradle and the error magically disappeared. This robot needs daily attention… it defeats the objective of automatically working. The model is simply bad and Roomba won’t replace it as, unknowingly, my Amazon order was not from an authorized retailer. Do not buy this product. I’ve owned about 5 Roombas before purchasing two of this models. Previous robots have been excellent. I need to tinker with the older models maybe twice a month. My only complaint is that they were loud. One product we’ve owned for almost 12 years by just periodically replacing the battery. This i3 model is a lemon. I purchased two to vacuum our first floor. They need to be tinkered with a couple of times per week. There is not one consistent issue… they are just always having problems. They’ve lost maps; disconnected from internet; bumper gets stuck; don’t find their way home; when they get home they don’t always charge… or empty the bag. They are quiet… so quiet sometimes the vacuum does not come on before they “finish the job.” Again, I don’t have major complaints about any of the other models I’ve ordered. These two suck. When I complained to customer service, I stated I wanted to replace these with a better model, they offered me a model that was $200 less on Amazon. When I disagreed and offered to pay the difference between the “better” models and this one, they said “well, Amazon got your money, not us, so that’s why we can’t (exchange)”. Usually their service is excellent and I’ve had many good experiences, but iRobot was unwilling to help me in a satisfactory way. This review is for the i3+ model only, and this model sucks. ... show more

  • Works great - now that it works
First the bad: The Roomba arrived non-functional. It was throwing an error code (27) from the first time I used it, which indicated after troubleshooting that the Cleaning Head Module needed to be replaced (a $65 part). I tried all the other options but in the end had to buy a new cleaning head module. Unfortunately, because the vendor I purchased from was not an authorized seller (it was third-party, not Amazon), it was not under warranty. If you want it to be under warranty, buy from the iRobot store on Amazon. Now the good: First, iRobot customer service was as helpful as they could be and genuinely tried to assist without charging me for a new part. Once I got the new cleaning head module and replaced the malfunctioning one, everything worked great. It is a little loud and you have to do some pre-cleaning (pick up throw rugs and cat toys, *ahem*) but it gets all the bits on the floor and permanent rugs and works its way around obstacles. I hate vacuuming, especially multi-floor; the Roomba does the downstairs, and i do the upstairs with my stick vac. All in all I'm happy, but I would have been happier if it had worked out of the box without expensive repairs. ... show more

  • Works well but has issues
So as far as the act of vacuuming, it works fairly well. I have a house full of shedding dogs and the robot does a pretty good job of staying caught up with it. As for the downsides or issues, there are just way to many for something at this high of a price point. Here is a partial listing: 1) Holy loud when it empties. Like a 747 landing in your living room loud. Definitely something that will surprise you the first time you hear it and will likely keep you from running vacuum jobs during bedtime hours 2) Speaking of emptying, it frequently struggles to empty itself. This is only made worse by the limited to no documentation on how to resolve it. After much Google searching and YouTube videos, I found you open it with the button on the side and occasionally the filter needs vacuuming off. I have had to vacuum my filter clean 3 times in 3 weeks... soooo.... there's that 3) It gets stuck A LOT. In fact, it just texted me that it "needs attention" because it got itself stuck again. 90% of the time it gets stuck on the base of a floor fan. The same fan. It's maddening. 4) The app needs work. It rarely connects the robot without having to crash and relaunch the app, even then it is iffy. Definitely needs some updates and love in this area Overall, I would say it is a decent robot, but it is waaaay too expensive for all of the issues with it. I would definitely recommend trying a cheaper or different brand until they iron the kinks out of this one. Side note, my 10+ year old Roomba still runs and, arguably, does as good a job, if not better, than this new model. The technology in them has definitely evolved, but I am not convinced it is all for the better. ... show more

  • So proud of our new family member!
I got this guy for Black Friday after months of research and over analyzing. It is our first robot vacuum and we have been dreaming about one for a long time. It has been about a month since his inaugural run and I have to say I love him just as much, if not more, than I did that first day. He is a little noisy but his running noise is very easy to ignore and not distracting, even if you are in the same room, and both my husband and I have some auditory sensitivities. The self empty 100% sounds like a jet taking off. It isn’t so loud that it affects me in my home office two rooms away, but it is in our den and it is definitely “pause the tv” loud in the den. However the self emptying process takes maybe about ten seconds so is very easy to work around. We have two dogs and two cats. One of those dogs is a Great Pyrenees so it is basically like having five dogs. One of our cats is a Maine coon mix so lots of very downy fluff floating around, mixing with the great white Pyr tumbleweeds. This little guy does so well with all the fur. Obviously we do need to keep an eye on the spinning sweeper and the rollers but their maintenance is lower than any previous vacuum so we are very happy. Both my husband and I grow our hair out to donate so there is a lot of long hair floating about and again our little guy is excellent with the lightest of maintenance. As previously mentioned we have two cats so kitty litter is a thing, we also have a “flinger” so despite our best efforts it does travel quite a bit, until it is time for him to make his run, then it is gone! He has done well on our wood floors, our stone floors, he even does well “off roading” on our brick fireplace. Our rugs look great too. I will say our only real struggle is our high pile carpet in our living room. It is an inherited home and that carpet is an area we have not gotten to renovating yet, so it is old, dirty and very plush. Think almost shag carpet but thicker. He definitely struggles to take care of it, trying to roll through all that fluff and trying to suck up accumulated dust, etc. from all that fluff, he almost always needs to take a little break to recharge before he completes the room. (Me too bud, me too!) However, he does make it through and it does look better than it has in years, so he is still doing a great job. With all that he has to tackle we have him scheduled to run twice daily and occasionally we will skip a run or block off rooms that have not been used. It would obviously be cool to have the options the other roombas have to create keep out zones or have specific tasks for them to do but it has not been that difficult to block off rooms or shut doors if need be. If he doesn’t have to tackle the living room carpet he can do his whole run without needing to recharge. I can not speak highly enough about how this little addition to our family has improved our life. To be rushing around to get ready for the tiny Christmas company we got to have, and have our little buddy running around helping, I can not explain how much of an impact that makes on our home and our mentality. This is not the perfect robot vacuum but for the money, he is above and beyond perfect for our family. Will definitely be a roomba “parent” for life! 😂 ... show more
